Answer:
Step-by-step explanation:
If two variables are the same when they are multiplied it becomes that variable squared.
8 x C x C
Answer: r < 389
Step-by-step explanation:
Hi, to answer this question we have to write an inequality:
Rushawn's possible finishing times (r) must be less (<) than Josie's finishing time (329) plus 60 seconds.
Mathematically speaking:
r < 329+60
r < 389
So, the correct option is the last one.
Feel free to ask for more if needed or if you did not understand something.
The two equations are vertical angles, which mean they are equal.
Set each equation to equal each other and solve for x.
3x-3 = 6(x-10)
Simplify the right side:
3x-3 = 6x-60
Subtract 3x from each side:
-3 = 3x - 60
Add 60 to each side:
57 = 3x
Divide both sides by 3:
x = 57 / 3
x = 19
Answer:
210 beats
